DIMENSION optical probe integrates OPM (optical power meter), VFL (visual fault locator), RJ45 cable tracker and sequence test and other functions. The optical probe is easy-to-use, and it can easily handle with the construction of various communication networks and different test scenarios. Thanks to the unique probe-type and non-contact universal interface design, field engineers do not need to carry a wide variety of other fiber patch cords, all tests can be completed with one optical probe.
